Document Multi ldap support

[Adam Young]

"When defining the URL for connecting to the LDAP server in the Keystone configuration, looking for a way to specify multiple LDAP servers for redundancy. For example if an AD domain controller were not available, Keystone would try an alternate domain controller."

This is suopported, but config comment does not indicatei t. Needs an update.

is there something specific you had in mind that needed updating? the config option reads correctly IMO:

# URL(s) for connecting to the LDAP server. Multiple LDAP URLs may be specified
# as a comma separated string. The first URL to successfully bind is used for
# the connection. (string value)

Hi Adam,

Kindly look at the following in configuration file for multi LDAP server URLs.

# URL(s) for connecting to the LDAP server. Multiple LDAP URLs may be specified
# as a comma separated string. The first URL to successfully bind is used for
# the connection. (string value)
#url = ldap://localhost

if there is something specific in your mind, then please discuss
